Solar cells are a promising, green energy source; however, cost and efficiency limitations prevent widespread adoption. This paper proposes a solar cell design that is cost-effective both in production and materials. The junction is made of copper (I) oxide and zinc oxide, which are oxides of earth-abundant metals. Furthermore, a wet chemistry fabrication process is used, making the production of such cells inexpensive and easily scalable. The process involves growing copper nanowires, plating zinc, oxidizing, and depositing a top contact. This is a greener manufacturing method of solar cells where no harmful compounds or excessive energy is used in fabrication.
